|
|
|
Slope of the Regression Line

Explanation:
Detailed explanation-1: -Answer and Explanation: Therefore, the percentage of the variation in y that can be explained by the corresponding variation in x and the least-squares line is 94.64% . The percentage which is unexplained is 5.36% i.e. (100%−94.64%) .
Detailed explanation-2: -The coefficient of determination (R²) is a number between 0 and 1 that measures how well a statistical model predicts an outcome. You can interpret the R² as the proportion of variation in the dependent variable that is predicted by the statistical model.
